Reirel, I am sorry for everything you have gone through. It is very scary. I hope you will ask your doctors for more information and perhaps seek a consult with Mayo, Cleveland Clinic or a major medical center. Is it a celiac aneurysm or something else? I have a celiac aneurysm and this condition is relatively rare so many doctors do not diagnose it or even know to look for it. Fortunately I live in a major city with excellent doctors and a university hospital. It was discovered last year after I had a splenic infarction which was caused by a clot from the celiac aneurysm (I also have stenosis at the same spot.) As a result my spleen mostly died from the lack of blood. They did not remove the spleen since that is no longer the usual protocol. My doctor is taking a wait and see approach since the aneurysm is relatively small. I see my internist twice a year and a vascular surgeon once a year. But that is what I have experienced and may be very different for you. I wish you the best and hope you will keep us posted. This group has been very helpful for me and we learn from each other.
